Making Your Own Tools

Forging metal means a lot of time standing over the fire, holding the metal – with tongs, obviously – in just the right place to get the proper amount of heat, and withdrawing it at just the right moment. Too much heat and it sparks and disintegrates, too little and no amount of hammering can budge it. Movie blacksmiths look like bodybuilders slamming white-hot metal with sledgehammers; the reality involves a lot more frantic and often delicate tapping, as the smith has only a few seconds to make the right changes before it cools again.
